Opening a GUI window during brew test leads to test failures on Yosemite.
pyqt: bottle against system Python

Closes #35283.

pyqt: update 4.11.1 bottle.
nacl: homepage move

The homepage has moved. Also added a mirror, and fixed the quotation
marks.

If it’s possible to get bottles for this, even not-completely-optimal
bottles, despite the weird make process, that’d be useful given the
15-20 minute compile otherwise.

Closes #35276.
